No problem. Roller cams are nice, but very expensive. You really don't need one if you follow the break-in rules of the cam maker. True, there is no need to break-in the cam, but the rest of the motor needs special care, so you might as well do it right at the start. Oil Warehouse will deliver to your door step if you can't find something local,

If you go with just the additive like Com Cams, choose a name brand oil to go with it. This works just as well as true break-in oil with a mild built engine. I will use the best I can get, Brad Penn, in all out race motors. Any oil will work, I just like the better brands, they may be all the same, but I feel better using a brand I know.
Wix oil filters are the best out there, Napa's best grade are made by Wix as well. I always buy two filters and change it after the break-in and a short drive. I leave the oil for a couple 100 miles. If the filter does its job, there is no use throwing good oil away. People always say the oil should be changed right away due to contamination. Check after it has run, you will know if it needs changed or not. I also use a lot of Moly cam grease, so the oil gets dark really quick, still doesn't mean its bad. Metal sparkles or brass sparkles are bad, dark oil is full of good useful additives.
Good luck with yours,
